Question

Using the code below, Complete the C program main.c to stop execution if the user attempts a divide by 0.

#include <stdio.h>

int main() {
float a, b;

printf("Input two integers to divide the first by the second\n");
scanf("%f%f", &a, &b);

printf("%f/%f = %.2f\n", a, b, a/b);
  
return 0;
}

Answer 1

JUST ADD A IF ELSE STATEMENT TO CHECK IF THE DIVISOR IS 0

#include <stdio.h>
#include <stdlib.h>
int main() {
float a, b;

printf("Input two integers to divide the first by the second\n");
scanf("%f%f", &a, &b);
if (b==0) #ADDED THE IF ELSE PART
{
printf("Division by Zero is not allowed");
fprintf(stderr, "Division by zero! Exiting...\n");
exit(EXIT_FAILURE);
}
else{
printf("%f/%f = %.2f\n", a, b, a/b);
}
return 0;
}
